HP Pavilion zd8000 CD/Optical Drive Replacement

Slide the battery release latch towards you.

Pull up on the battery to remove it.

Remove the 8mm Philips screw located between the hard drive and the WiFi card.

Turn the laptop 90 degrees clockwise so you are facing the CD drive.

Unbend a paperclip and insert the end into the small hole by the eject button to cause the tray to pop out towards you.

Gently pull the tray away from the laptop and the rest of the optical drive will follow.
